Description

  The present invention relates to a foreign language conversation training system, and in particular, in the acquisition of foreign language conversation skills, diversified correction of learner's conversation contents, pronunciation, intonation, conversation speed, and the like, and improvement of language operation ability in conversation. The present invention relates to a foreign language conversation training system in which training for improvement can be efficiently performed without involving a native language.

  Japanese people are generally not good at speaking English and other foreign languages. The reason for this is that in school classes from compulsory education to higher education, the emphasis has been placed on literacy. In addition to the factors of long-term history, linguistically differences in word order in sentences, differences in vocalization methods and pronunciations, Japanese in which sentences clearly pronounce words one by one, such as English There are various factors such as differences in language customs, such as connecting languages and omitting some sounds.

  In such situations, strategies to improve foreign language speaking skills include practicing to be able to speak with correct grammar and words in order to communicate accurately with the other party. It is. In addition, practice to be able to speak with correct pronunciation, intonation, and conversation speed as much as possible.

  In order to support the practice, it is necessary to create a video teaching material assuming an actual dialogue scene, and the instructor and the learner interact in the teaching material.

In this regard, conventional audio and video tapes, optical discs, and other recordings and recorded conversational teaching materials use standard conversation scenes and listen to sentences contained in those media, and repeat them accordingly. I could only practice.
Recently, various learning systems have been proposed with the development of Information & Communication Technology (ICT). For example, Patent Literatures 1 to 4 disclose various foreign language education, conversation training, and language learning systems.

JP 2002-189403 A JP-A-5-341705 JP 2014-145976 A JP 2011-85641 A

  However, in the learning training system using the conventional information communication technology, including the above-mentioned Patent Documents 1 to 4, the user listens to a dialogue scene included in the recorded and recorded conversational teaching materials and views it. The training system was practiced by repeating the street, or by using information and communication technology (ICT), the training system was narrowed down to a narrow area such as pronunciation only.

For this reason, the learner could not practice while pointing out and correcting problems and weaknesses in the grammar, words, pronunciation, intonation, conversation speed, etc. in the content spoken by the learner.
Also, it is difficult to practice speaking by incorporating your own information (name, date of birth, place of birth, hobbies, etc.) into the text, and it is very difficult to efficiently improve the practical useful conversation skills. Was.

  The present invention has been made in view of such conventional problems, and in learning a foreign language's conversational ability, the learner's dialogue content, pronunciation, intonation, diversified correction of conversation speed, etc. An object of the present invention is to provide a foreign language conversation training system in which practice for improving operational skills can be efficiently performed without involving a native language.

  Hereinafter, embodiments of the present invention will be described. FIG. 1 shows an overall configuration diagram of a foreign language conversation training system according to an embodiment of the present invention. In FIG. 1, the Internet 1 has a management unit 3 for managing a conversation training system in a foreign language, a data storage unit 5 storing training materials, and data for transmitting and receiving data to and from a local via an interface 7. A center server 10 having a transmitting / receiving unit 9 is connected. The center server 10 is connected to at least one information terminal device 20 via the Internet 1. The information terminal device 20 is configured to download training materials as contents from the center server 10.

  The data downloaded by the data transmission / reception unit 9 via the interface 21 is stored in the teaching material storage unit 25 of the information terminal device 20. A microphone 27 is built in or connected to the information terminal device 20, and a voice picked up by the microphone 27 is converted into a digital signal by a voice extraction unit 29 in the information terminal device 20. The speech extracted by the speech extraction unit 29 is converted into text as speech by the speech analysis unit 31. However, the voice analysis unit 31 may have a structure in which a text as a speech is input from the teaching material storage unit 25 to be converted into a voice.

   The teaching material data stored in the teaching material storage unit 25 is played back by the playback unit 33 and displayed on the display unit 35. The evaluation unit 37 determines how much the speech extracted by the speech extraction unit 29 or the text converted by the speech analysis unit 31 matches the speech data or text stored in the teaching material storage unit 25 in advance, or differs. Is determined.

As described above, the teaching material storage unit 25 may store the model voice data, but may compare the model text with the voice converted from the model text each time the evaluation is performed.
The arithmetic unit 39 performs various arithmetic operations required for the operation of the conversation training system. In addition, when the learner operates the keyboard 41 with keys, the learner's unique information is stored in the unique information storage unit 43.

  The information terminal device 20 can be any information terminal device that can be connected to the Internet, such as a wearable computer (eg, glasses), a smartphone, a tablet computer, a PDA, a game machine, an electronic dictionary, a navigation terminal, a personal computer, and a digital television. Good.

  The training materials are, for example, an action image of a conversation exchange of a set conversation scene, a conversation voice, and a dialogue (text). In addition, an action image of only a non-learner (a conversation partner) in the conversation, a conversation voice, and a dialogue (text) may be used. Further, it may be a voice of a basic sentence, a dialogue (text), and a moving image, a still image (photograph), a picture, a design, a graph, or the like associated with the learner.

Next, a training method by a foreign language conversation training system according to an embodiment of the present invention will be described based on a conceptual flowchart and a screen transition diagram.
In this foreign language conversation training system, the information terminal device 20 allows the user to select from a plurality of different conversation practice types (practice types). Then, on the display screen of the information terminal device 20, an image with sound of a dialogue scene or a scene where the lecturer is speaking is displayed.

  The learner can speak the designated part of the person with the instructor interactively, repeat the indicated sentences, think and write out the sentences according to the instructions of the instructor, and follow the instructions of the teaching materials themselves. After inputting the information and saying the text aloud, each content is evaluated from multiple perspectives and comprehensively, and mistakes, weaknesses, and problems are communicated to the learner to correct the learner. It is a conversation training system with a mechanism that repeatedly performs this while prompting the user.

  In addition, by using a glasses-type wearable computer for the information terminal device 20, it is possible to create a situation similar to a dialogue scene viewed from the user's point of view, thereby increasing the sense of realism or real conversation with the instructor. Creating situations similar to that described above has a positive effect on improving conversational ability.

In the conceptual flowchart of FIG. 2, in step 1 (abbreviated as S1 in the figure; the same applies hereinafter), the information terminal device 20 in which application software is installed in advance is started.
When the application software starts, a menu is displayed as shown in step 2. As a screen configuration, a screen 1 of FIG. 7 (abbreviated as P1 in the figure; the same applies hereinafter) is displayed. The learner specifies a desired one of the three items. Of the three items, the first is "practice on a new theme", the second is "practice on a recommended theme", and the third is "view practice history".

  In the first "practice with new theme", the list of training material themes prepared in advance by the provider of this conversation training system is displayed in step 3, and the learner practices in step 4 out of them. Select the theme you want. This theme includes, for example, “first face-to-face conversation”, “self-introduction”, “ask for directions” and the like as shown in screen 3.

  The second “Recommended Themes with Practices” is a list of themes that the learner has practiced in the past and needs more practice is displayed in step 5. For example, as shown in the screen 5, this theme is displayed as items such as "shopping" and "mealing", and is provided by the provider in advance. In step 6, the learner selects a theme to practice in.

   The third item “view practice history” is displayed as items such as “shopping” and “eating” as shown in the screen 7. As the processing flow, the practice history is automatically extracted and displayed based on the history of the practice performed by the learner in the past and their results in step 7. Each item may be displayed together with the grade. In addition, the learner may be allowed to select a theme to be practiced from the displayed items.

In each screen, the learner can return to the main menu (abbreviated as MM in each screen) after browsing the contents.
When the selection in step 2 is performed, the selected training material is downloaded from the center server 10 in step 8 and read into the information terminal device 20. However, the practice teaching material of the theme selected from a storage medium such as a DVD may be directly read into the information terminal device 20.

  In the foreign language conversation training system of the present invention, as shown in step 9, three types of practices, type A, type B, and type C, are set. The learner then chooses the desired practice. As shown in screen 9, type A is a conversation practice. In this conversation practice, a conversation exercise that has been created in advance is shown to the learner in the form of images, sounds, and dialogue text on the screen, and is then performed in a negotiating style between the instructor and the learner.

  Type B is a replacement practice. In this replacement practice, the instructor shows the learner a basic sentence created in advance in the form of images, sounds, and dialogue text on the screen, and then the learner repeats. After that, a part of the basic sentence is replaced by the instructor, and the learner repeats the process of creating a correct sentence using the replaced phrase and responding by voice. The replacement phrase is, for example, a subject, a verb, an object, or the like, and is at least one word.

   Further, type C is my practice. This My Practice uses the learner's own information about the conversation exercises and basic sentences created in advance from the keyboard 41 or the like, saves it in the unique information storage unit 43, and uses this unique information. It is used to exchange conversations with the instructor and exchange words in basic sentences.

  Note that each practice does not necessarily require all of the images, sounds, and dialogue texts, and can be configured with at least one of them.

First, a method of executing the type A conversation practice will be described.
In the type A conversation practice, the conversation practice is executed in step 10 of FIG. 3 and an example conversation is introduced in step 11. This introduction is performed by showing the learner a conversation exercise prepared in advance by the provider of the system using images, sounds, and dialogue text on the screen.

  Specifically, reproduction of the conversation is started on the screen 11 of FIG. 7, and the learner listens to the sample conversation on the screen 13 by listening to the screen and voice. The screen may be played by a real person or created as a cartoon. If the learner wants to view the content again because he / she cannot fully understand it, the user can press the button again as shown in step 13 (corresponding to the screen 15 in FIG. 8) so that the user can view the content again.

  When the trial listening is completed, the learner presses the “next” button in step 13 of FIG. 3 (corresponding to the screen 15 of FIG. 8). Then, in step 14 (corresponding to the screen 17), the display of the practice screen is selected. In this case, when the learner performs the conversation practice, the learner selects whether to display the dialog of the instructor and the learner in text on the screen or not.

  First, a case where a mode in which dialogue is displayed as text on a screen is selected will be described. In this case, the conversation practice starts in step 15 (corresponding to the screen 19). From here, the practice is conducted in a style of interaction between the instructor and the learner. The screen 21 is the part of the instructor who speaks to the learner by video and audio. The instructor and learner's dialogue text is displayed as a telop at the bottom of the screen.

   Step 16 (corresponding to the screen 23) is the part of the learner, who responds to the instructor. In other words, in response to the speech from the instructor, the learner replies with the dialogue of his part. The replied voice is extracted by the microphone 27. Repeat the instructor part and the learner part. In this way, the conversation is advanced by repeating the exchange with the instructor. If the learner wants to watch again because he / she cannot understand enough, the user can press the button again as shown in the screen 25 to view again.

  In step 17, the response of the learner is evaluated and scored. The response of the learner in the conversation is evaluated and scored (scored) from the five points of correctness, pronunciation, intonation, reaction time, and comprehensive evaluation of the response content, respectively. The correctness of the reply content is determined, for example, as follows. That is, after the returned voice is converted into a text by the voice analyzing unit 31, the correct text stored in the teaching material storing unit 25 is compared with the texts, and the matching degree is calculated by the evaluation unit 37, and the correctness is calculated. Judge.

  However, the voice replied by the learner may be input to the evaluation unit 37 in a form in which the correct text stored in advance in the learning material storage unit 25 is voice-converted by the voice analysis unit 31, and the voices may be compared. . In this case, the correctness is determined based on the degree of coincidence between the voices. In this case, correctness is determined by comparing the degree of coincidence with a preset threshold value.

  The pronunciation, intonation, and reaction time are performed by analyzing the speech of the learner extracted by the speech extraction unit 29 with the speech analysis unit 31. This voice analysis can be performed by using a well-known and widely used voice recognition technology. The voice analysis is performed using, for example, a frequency pattern.

In the comprehensive evaluation, for example, each of the items of the correctness of the response content, pronunciation, intonation, and reaction time is evaluated on a 100-point scale as elements A, B, C, and D. On the other hand, the overall evaluation T (%) is calculated by the calculation unit 39 as in Equation 1 with weights of the respective elements being a, b, c, and d. The weights a, b, c, and d are, for example, 1.
(Equation 1)
T = (a × element A + b × element B + c × element C + d × element D) × 100 / (a + b + c + d)

   In step 18 in FIG. 3 (corresponding to the screen 27 in FIG. 9), the result of evaluation and scoring is displayed on a screen, for example, as a pentagonal radar chart. The radar chart may be displayed on the screen 23 in real time on the side of the screen instead of being shown again as the screen 27. The radar chart allows learners to see their improvements and continue their practice.

  In step 19 (corresponding to the screen 29 in FIG. 9), the learner can end the practice. When continuing the practice, the learner returns to step 11 "Introduction of sample conversation" to view the entire conversation by the instructor again and then resumes the practice, or the learner selects "display of practice screen display" in step 14. To return to displaying the text of the dialogue or not to reverse, and then resume the practice.

   The results of evaluation and scoring are compiled as practice data for each theme, sent to the center server 10 as shown in step 51 of FIG. 2, and a history of practices is taken in the management unit 3 in step 52. I have. In step 53, a practice theme is recommended to the learner based on the history of the practice, and the history is disclosed to the learner. The recommendation of the practice theme is performed by, for example, extracting a theme with poor performance.

  In addition, by collecting the statistics of the history for a plurality of learners, it is possible to find a difficult conversation theme common to a plurality of learners. In addition, it is possible to find a conversation theme that is frequently used by a plurality of learners and is easily attracted. Based on this information, new teaching materials can be efficiently developed in a form tailored to the learner.

  However, the center server 10 is not always indispensable, and the foreign language conversation training system according to the present embodiment can be realized even with the configuration of only the information terminal device 20.

  Next, a case where the mode in which the dialogue is displayed in text on the screen is not selected will be described. When a mode in which no dialog text is displayed is selected on the screen 17 in FIG. 8, the text is not displayed in the telop as shown in the screens 31 to 41 in FIG. Therefore, it can be used as a more advanced level. As the flow of the processing, the screens 19 to 29 correspond to the screens 31 to 41, respectively, and the description is omitted.

Next, a method of executing the type B replacement practice will be described.
This replacement practice is executed in step 21 of FIG. 4 (corresponding to the screen 43 of FIG. 9). First, the learner listens once or repeatedly to the model conversational video including the instructor part and the learner part in steps 23 to 24 of FIG. 4 (corresponding to the screens 45 to 49 of FIG. 9). I do.

  When the trial listening is completed, the learner presses the “next” button in step 24 (corresponding to the screen 49 in FIG. 10). Then, in step 25 (corresponding to the screen 51), the display of the practice screen is selected. In this case, when the learner performs the conversation practice, the learner selects whether the dialog of the instructor and the learner is displayed as text on the screen or not.

  First, a case where a mode in which dialogue is displayed as text on a screen is selected will be described. In this case, the conversation practice starts in step 26 of FIG. 4 (corresponding to the screen 53 of FIG. 10). The screen 55 is a part of the instructor, and the instructor speaks to the learner by video and audio. The text of the instructor's dialogue is displayed as a telop at the bottom of the screen.

  In step 27 (corresponding to the screen 57), the learner repeats the line (for example, I sent to the hospital yesterday) spoken by the instructor. The repeated sound is extracted by the microphone 27. If the learner does not understand enough and wants to view again, the user can press the button again as shown in a screen 59 in FIG. 11 to view again.

  In step 28 of FIG. 4, the response of the learner is evaluated and scored. In step 29 (corresponding to the screen 61 of FIG. 11), the result is displayed on a radar chart. Subsequently, in step 30 in FIG. 5 (corresponding to the screen 63 in FIG. 11), the instructor provides voice guidance for the replacement word tomorrow instead of, for example, yesterday. This text is also displayed on the telop.

  Step 31 (corresponding to the screen 65) is a part of the learner, and the learner replies with a sentence in which this word is replaced. The reply voice is extracted by the microphone 27. The method of guiding the instructor who provides the exchanged words is not only the voice guidance but also showing the text directly or showing the picture (for example, an apple figure) to the learner and giving the learner a word (apple) related to the picture. It may be implemented by reminding the user.

In step 32, the response of the learner is evaluated and scored, and in step 33 (corresponding to the screen 67), the result is displayed on a radar chart on a screen.
In step 34 of FIG. 5 (corresponding to the screen 69 of FIG. 11), the learner can end the practice. When continuing the practice, the learner returns to step 23 “the instructor introduces the basic sentence” and again listens to the conversation by the instructor and resumes the practice, or the step 25 “selects the display of the practice screen”. You can choose to go back to displaying the text of the line or not, and then restart the practice.
The results of the evaluation and scoring are compiled as practice data for each theme, sent to the center server 10, and the history is taken by the management unit 3.

Next, the case where the mode in which the dialog is displayed in text on the screen in step 25 (corresponding to the screen 51 in FIG. 10) in FIG. 4 is not described will be described.
When a mode in which no dialog text is displayed is selected on the screen 51 in FIG. 10, the text in the telop is not displayed as shown in the screens 71 to 87 in FIG. Therefore, it can be used as a more advanced level. As the processing flow, the screens 53 to 69 correspond to the screens 71 to 87, respectively, and the description is omitted.

Next, a method of executing type C my practice will be described.
This replacement practice is executed in step 35 of FIG. 6 (corresponding to the screen 89 of FIG. 12). First, at step 36 (corresponding to the screens 91 and 93), the learner inputs text in a question and answer format using a text input device such as the keyboard 41. This text input may be by voice input.

  This text is, for example, unique information on the individual learner. As shown in screens 91 and 93, the question "Your place of second?" On the other hand, the learner inputs "Tokyo". However, the information is not necessarily limited to information on the individual learner. Further, the input may not be based on the question and answer. The input data is stored in the unique information storage unit 43.

  Subsequently, the display of the practice screen is selected in step 37 of FIG. 6 (corresponding to the screen 95 of FIG. 12). In this case, when the learner performs the conversation practice, the learner selects whether the dialog of the instructor and the learner is displayed as text on the screen or not.

  First, a case where a mode in which dialogue is displayed as text on a screen is selected will be described. In this case, the conversation practice starts in step 38 of FIG. 6 (corresponding to the screen 97 of FIG. 13). The screen 99 is the part of the instructor, who speaks to the learner by video and audio. The text of the instructor's dialogue is displayed as a telop at the bottom of the screen.

  In step 39 (corresponding to the screen 101), the learner replies to the dialogue of the question (for example, Where there you born?) Spoken by the instructor. The voice of the reply is, for example, I was born in Tokyo, and the portion of Tokyo is an information portion unique to the learner. The voice replied here is extracted by the microphone 27. Since the text of Tokyo is stored in the unique information storage unit 43 in advance, it is possible to make a right / wrong comparison or the like after voice / text conversion in the same manner as described above.

In step 40, the response of the learner is evaluated and scored, and in step 41 (corresponding to the screen 103), the result is displayed on the screen in a radar chart.
In step 42 (corresponding to screen 105), the learner can end the practice.

When continuing the practice, the learner returns to the “Lecturer Conversation Section” in step 38 to view the conversation by the instructor again and resumes the practice, or the learner selects the “display of practice screen” in step 37. You can choose to go back and display the text of the dialog or not, and then restart the practice.
The results of the evaluation and scoring are compiled as practice data for each theme, sent to the center server 10, and the history is taken by the management unit 3.

  Next, the case where the mode in which the dialogue is displayed in text on the screen in step 37 (corresponding to the screen 95 in FIG. 12) in FIG. 6 is not described will be described. When a mode in which no dialog text is displayed is selected on the screen 95, the text in the telop is not displayed as shown in the screen 107 in FIG. 13 to the screen 115 in FIG.

Therefore, it can be used as a more advanced level. The flow of the processing will not be described because the screens 97 to 105 correspond to the screens 107 to 115, respectively.
When a wearable computer (glasses or the like) is used as the information terminal device 20 as shown on a screen 120 in FIG. 7, it is possible to practice as if having a conversation with a person.
